Hisei Nishiki - lost all it's hi Hn

With Doitsu fish, the risk of loosing your hi is greater than with Wagoi fish. It is also more difficult to see the signs that it might happen.

I have also learned that it happens more frequently with metallic fish.

I have also learned that it seldom happens with Japanese imports as opposed to local bred fish.

This one is doitsu and metallic, (Hisei Nishiki) but I imported it from a highly respected Japanese breeder being Aoki, and you don't expect this vast change from his fish as he specialises in Hisei Nishiki's. (Genetics are very important)

The quality of water also plays a major role. The harder the water, the stronger the possibility that your koi might loose it's hi.

This one lost all it's red within five months. The black became a little bit stronger and the alignment of scales on the dorsal line became better.

Hi,

I would think that for a Koi to lose its color that fast, (five months) stress could be the responsible factor.
Koi can lose its color within days due to stress.
If there is a color lost over a longer period and to older Koi, genetics would play a major part.

I have found that Tancho Kohaku is the most likely of all Koi to lose it Hi. Colors like Hi(red), Ki (Yellow) Oranji (Orange) are there for the once that will disappear.

Harder water is also one of the reasons that Koi develops “shimis.” (Small black specks, which sometimes spoil the appearance of the white (Shiroji) or red (Hi) markings of a Koi.)

Hi guys I am rather new on this site but would also like to say this.
I bought a doitsu showa also from aoki and the red is busy going fast and I have only had this fish for 6 weeks.
My water was very soft like in 0 GH and <30 KH as well.
So I think I will go along with the stress theory but then the dealer where I bought mine still has some left and they are fine.
I am now hardening my water up to 150 GH and 100 KH and I hope this will help.
Will keep you posted on developments.

Hi Jaco
As el nie seker was nab die oorsprong ja maar ek is baie seker dit het ban Aoki af gekom.
Ek is so teleurgestel en sal nou nie maklik weer n doitsu vis koop tensy dit klaar groot is nie.

You get water softner units but it is expensive.

You can add chemicals, but then you have to add all the time. Salt will soften the water and Bentonite clay.

If your water are more or less fine, leave it as is and don't mess around with additives, although clay and/or salt is fine.

Just my opinion.

The reason i ask is because my doitsu kohaku is developing tiny black specks, and my sanke's are loosing their red. From reading this posts i came to the conclusion that softening my water will help the red in my fish. If i add salt whats the max % that i can safely go up to?

I would listed to Admin.
Dont add anything. Salt is an irritant, and Koi is not a salt water fish...
Use salt as treatment for diseases and parasites. If U keep your Koi in salt all the time bacteria and parasites can become resistant to salt.
My water is hard also: very hard with high PH.
We just have to live with it.
Try and buy grown fish, with good genetics. It helps.
